Verifying Raw Flax Traceability from Field to Scutcher
Verify raw flax origin by matching field cadastral logs to weighbridge moisture tickets, scope certificates, and scutching mass balance yield ratios.
Long Fibre
Material Classification
High-grade cellulosic strands obtained from the scutching process form the primary raw material for premium linen yarn. This long fibre, which can reach lengths of sixty to ninety centimeters, is characterized by its strength and parallel alignment within the flax stem. Unlike short tow fibres, these long strands require gentle mechanical handling to prevent breaking during the hackling process.
They represent the most valuable output of the scutching mill and are graded according to their color, cleanliness, and tensile strength.
Mill Processing
Wet spinning is the preferred manufacturing method for these long bundles because it allows the fibres to slide and align more uniformly. Chinese mills rely on imported European straw to secure a consistent supply of long fibre for their fine yarn production lines. The processing begins with hackling, where the fibres are combed through progressively finer steel pins to remove remaining wood fragments and short fibres.
This step creates a continuous sliver that is ready for the spinning frame. Proper combing is necessary to maximize the yield of fine yarn from the raw material.
Fabric Attribute
Woven fabrics produced from these high-quality yarns exhibit a smooth surface with minimal hairiness. The inherent strength of the long strands makes the yarn highly resistant to friction and abrasion during the weaving process. This durability makes the finished linen cloth suitable for luxury apparel and durable household linens.
